--- Comment #3 from James Th <ja...@thornber.io> --- what you say makes total sense! :) So, I used buetoothctl, and this was the result: luetoothctl Agent registered [NEW] Device 28:C1:3C:A2:91:02 Wireless Controller [bluetooth]# scan on Discovery started [CHG] Controller D4:6D:6D:53:46:06 Discovering: yes [bluetooth]# devices Device 28:C1:3C:A2:91:02 Wireless Controller [CHG] Device 28:C1:3C:A2:91:02 Trusted: yes [bluetooth]# pair 28:C1:3C:A2:91:02 Attempting to pair with 28:C1:3C:A2:91:02 Failed to pair: org.bluez.Error.ConnectionAttemptFailed [bluetooth]# So it must be failing earlier in the stack. So I know this is no longer a KDE issue, but do you have any ideas at all please?
